We measure the decoherence of a spatially separated atomic superposition due to spontaneous photon scattering. We observe a qualitative change in decoherence versus separation as the number of scattered photons increases, and verify quantitatively the decoherence rate constant in the many-photon limit. Our results illustrate an evolution of decoherence consistent with general models developed for a broad class of decoherence phenomena.
我们测量了由于自发光子散射导致的空间分离原子叠加态的退相干。随着散射光子数量的增加，我们观察到退相干与分离之间的定性变化，并在多光子极限下定量验证了退相干速率常数。我们的结果说明了退相干的一种演变，这与为广泛的退相干现象所开发的一般模型相一致。
